What we think of in our daily life involves finding answer to two valued questions: like "Is the action RIGHT or WRONG"? Is this statement TRUE or FALSE?
Such type of decision statements which result in YES or NO, RUE or FALSE. RIGHT or WRONG are binary decisions. In electronics it is used in addition to describe circuits whose state can be either 1(true) or 0 (false). Two-state logic or proposition had a major influence on Aristotle, who worked out precise methods for getting to the truth.
Then Augustus de Morgan found the link between logic and mathematics. But it was George Boole who invented a new kind of algebra by putting it all together. therefore it is known as Boolean Algebra.
Boolean Algebra is he algebra of binary variables. Binary variables are also known as Boolean Variables. Boolean variable can have only two values, 0 and 1. he mathematical operations available are AND, OR, and NOT.
